To all whom it may concern:

Be it knownthat I, MIOHAEL CAVANAGH, a citizen of the United States of America, re siding at New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new anduseful Improvements in Gages for Skiving-Machines, of which the following is a specification.

This invention relates to gages for skiving machines and is intended as an improvement on the type of gage described in Letters Patent No. 876,772 granted me under date of January 14:, 1908. In the patent mentioned there is described a gage for the purpose indicated which has a reversible wear-resisting plate with which the counters to be skived come in contact. The wear-resisting plate can be reversed so as to resent eight unworn corner-surfaces to t e action of the counters before being completely worn out.

The object of this invention is to increase the life of the gage by providing a construction in which double the number of new unworn surfaces may be used.

With this end in view the invention consists in a gage for skiving machines in which the reversible Wearingplate is divided into two sections, so that two reversible wearing lates are provided, said sections or plates eing held in position beneath the clamping block by improved fastening means, as will a pear from the following description and c aims. 1

In the accompanying drawing, Figure 1 is a perspective view showing the mannerin which the gage is mounted, Fig. 2 is a vertical longitudinal section of the gage; and Fig. 3 is a bottom view of the gage,

In the drawing 5 indicates the rotary feed table, 6 the feed-roll and 7' the knife in connection with which the gage is used. These parts are all as described in my previous patent. The gage 9 is located tangentially to the feed-table upon a suitable support 8 at the side of the latter.

The invention consists in roviding a gage the wear-resisting part ofw 'ch is formed in two plates or sections 10, which are secured in position beneath the clamping block 11. The sections 10' are laced end to end heneath the clamping lock and extend beyond the latter in the same way as the single wearing plate in the patent referred to. The clam ing block has at either end a hole 12 throug which screws 13 pass downwardly into the fixed part 8, said screws holding the sections 10in position by means of holes 14 formed in the latter. Each section 10 has two such holes 14 so that it may have its ends reversed with respect to the clamping plate. The ends of the sections 10 are indented at 15 so as to fit about a pin 16 extending downward from the clamping block 11 at the center of the latter. By means of thefastening screws and said pin the sections 10 are each secured at two points so as to be held firmly in position beneath the clamping block.

It will be understood that by this construction two wearing lates are provided, each of which is reversible, so that the number of unworn surfaces which may be presented to the action of the counters by reversing the sections 10 is double that of the surfaces of the single wearing plate used in my patented gage referred to. Each section 10 can be turned over and also have its ends reversed, it being held in position by means of 'one' of the fastening screws in connection with the pin 16 about which both of its ends are adapted to lit by means of the indentations or recesses 15.

In spite of the fact that two wearing plates are employed, the fastening of said plates is tion to the point where the fastening screws 'pass through them, so that the wearing plates are firmly held in place by using only one screw for each. In this manner only two screws-are needed for the entire device, as according to my previous patent.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A gagefor skiving machines comprising a clamping block, and two reversible wearing plates placed end to end and clamped in position beneath the same.

2. In a gage for skiving machines, the com bination of a clamping block, two reversible wearing plates beneath'said block extending beyond the same at its ends, fasteningscrews passing through said clamping block and said plates and securing each of the latter in position at one point, and means by which the Wearing plates are held in position beneath the block at their adjacent ends.

3. A gage for skiving machines comprising reversible wearing plates having two screwholes, a clamping block, and fastening screws l In testimony, that I claim the foregoing as passing through said block and through one my invention, I have signed my name in 10 of the holes in each plate. presence of two subscribing Witnesses.

4. A gage for skiving machines comprising MICHAEL GAVANAGH;

5 a clamping block having a pin on its undersurface, Wearing plates having indented ends Witnesses: to fit about said pin, and a fastening screw PAUL GOEPEL, securing each Wearing plate to said block. I HENRY J. SUHRBIER.
